TL;DR: Service account sprawl, hard-coded credentials, and weak offboarding leave many organisations unable to monitor or revoke non-human access effectively, according to StrongDM’s guide on privileged service accounts. The governance gap is no longer about awareness but about replacing manual control assumptions that fail at enterprise scale.
Editorial analysis by NHI Mgmt Group, based on content published by StrongDM: “Service Accounts: Definition, Best Practices, Security, and More”.
By the numbers:
- More than half of IT security professionals still rely on manual methods for managing privileged accounts, with 18% keeping records on paper and 36% using spreadsheets.
- Only 30% of enterprises discover all their privileged accounts, and 40% do not even bother looking for them.
Key questions
Q: What breaks when service accounts are managed with spreadsheets and manual PAM reviews?
A: Manual PAM breaks when service accounts outnumber the review process.
Q: Why do service accounts with standing privilege create such high breach risk?
A: Because a stolen or leaked machine credential often has direct access to production systems, support tools, or data stores without extra user prompts.
Q: What are the signs that service account governance is failing in an organisation?
A: Common warning signs include accounts with no clear owner, broad permissions that exceed job need, credentials stored in insecure places such as code or configuration, and service accounts that survive staff departures without reassignment.
Practitioner guidance
- Build a live service account inventory Discover every service account across servers, databases, containers, and cloud services, then attach owner, purpose, and environment metadata to each identity.
- Classify service accounts by business criticality Separate high-risk accounts from low-risk ones so that recovery, review, and remediation priorities reflect operational impact rather than account age.
- Remove hard-coded and reused credentials Replace embedded secrets with centrally managed credentials and coordinate rotation against application dependencies before revoking the old secret.
Bottom line: Service account sprawl exposes a basic identity governance gap because manual controls cannot keep pace with the number and persistence of non-human accounts.

Service account sprawl is an identity governance problem, not just an access-management problem. The article shows that once service accounts multiply across cloud, containers, and legacy systems, manual PAM stops being a control and becomes a record-keeping exercise. The practical consequence is that ownership, lifecycle state, and effective privilege drift apart. Organisations should treat service account sprawl as a governance failure mode that requires authoritative inventory, not a housekeeping issue.
A few things that frame the scale:
- Only 5.7% of organisations have full visibility into their service accounts, according to the Ultimate Guide to NHIs.
- 49% of IT professionals would prioritise improving privileged access management if the decision were theirs alone, according to Netwrix's 2023 Hybrid Security Trends Report.
A question worth separating out:
Q: How should organisations handle service account offboarding and credential rotation?
A: Treat offboarding and rotation as one workflow. Remove the account only after dependencies are mapped, then rotate or replace any shared secret that other workloads still rely on. Offboarding without dependency review creates outages, while rotation without lifecycle ownership leaves the same identity active and unaccountable.
